The XS Sights Big Dot Tritium Front Sight (brand part number SG-2003-3) glues directly over an existing front bead to give a defensive shotgun a faster, more visible sight picture in any light. XS Sights builds the front sight around a tritium insert that keeps glowing after the sun goes down, a real advantage for a home-defense gun that might get used well after dark. It’s compatible with beads measuring 0.120 to 0.140 inches in diameter and may require opening up the bead hole slightly by drilling and tapping for a proper fit. The sight is built for Mossberg, Remington, and other shotguns with a bead mounted directly to the barrel, and it’s a stand-alone solution that does not work with a rail or Ghost Ring setup.
